The Hub Ports Suspend Register (Figure 16-8) and Hub Ports Resume Status Register (Figure 16-9) indicate the suspend and
resume conditions on downstream ports. The suspend register must be set by firmware for any ports that are selectively
suspended. Also, this register is only valid for ports that are selectively suspended.
If a port is marked as selectively suspended, normal USB traffic is not sent to that port. Resume traffic is also prevented from
going to that port, unless the Resume comes from the selectively suspended port. If a resume condition is detected on the port,
hardware reflects a Resume back to the port, sets the Resume bit in the Hub Ports Resume Register, and generates a hub
interrupt.
If a disconnect occurs on a port marked as selectively suspended, the suspend bit is cleared.
The Device Remote Wakeup bit (bit 7) of the Hub Ports Suspend Register controls whether or not the resume signal is propagated
by the hub after a connect or a disconnect event. If the Device Remote Wakeup bit is set, the hub will automatically propagate
the resume signal after a connect or a disconnect event. If the Device Remote Wakeup bit is cleared, the hub will not propagate
the resume signal. The setting of the Device Remote Wakeup flag has no impact on the propagation of the resume signal after
a downstream remote wakeup event. The hub will automatically propagate the resume signal after a remote wakeup event,
regardless of the state of the Device Remote wakeup bit. The state of this bit has no impact on the generation of the hub interrupt.
A resume bit is set automatically when hardware detects a resume condition on a selectively suspended downstream port. The
resume condition is a differential ‘1’ for a low-speed device and a differential ‘0’ for a full-speed device.
These registers are cleared on reset or USB bus reset.

Set to 1 if D+ > D- (forced differential 1, if signal is differential, i.e. not a SE0 or SE1). Set to 0 if D- > D+ (forced differential
0, if signal is differential, i.e. not a SE0 or SE1).
Set to 0.
Set to 1 if Port x is Selectively Suspended; Set to 0 if Port x Do not suspend.
When set to 1, Enable hardware upstream resume signaling for connect/disconnect events during global resume.
When set to 0, Disable hardware upstream resume signaling for connect/disconnect events during global resume.
